What documents should I see?

The registration book (CR), the seller's national ID, and ideally service records and the revenue licence. The name in the CR should match the seller, or they should have the owner's written permission.

Should I get a mechanic to inspect it?

Yes, for any used vehicle. A mechanic can spot problems that are easy to miss on a test drive.

Check the documents first (registration book, seller ID, chassis and engine numbers), then the body, tyres, engine, gearbox and electrics, take a test drive, and have a mechanic you trust inspect the vehicle before you pay.

Documents

The name in the registration book matches the seller's ID.
The chassis and engine numbers on the vehicle match the registration book.
Ask whether the vehicle is under a lease or loan that still has to be settled.

Outside

Check	What to look for
Body panels	Uneven gaps or paint colour can mean accident repairs
Tyres	Even wear; uneven wear can point to alignment problems
Lights and glass	Cracks, condensation inside lamps

Inside and under the bonnet

Warning lights should come on at start-up and then go off.
Look for oil or coolant leaks and listen for unusual engine noises.
Test the air conditioning, windows, mirrors and every switch.

Test drive

Drive at different speeds. The gearbox should change smoothly, the brakes should pull straight, and the steering shouldn't vibrate.
